ADM2483BRWZ-REEL

Overview

The ADM2483BRWZ-REEL is an integrated isolated RS-485 transceiver utilizing iCoupler magnetic coupling technology. It operates on a single 5V or 3.3V supply with a maximum quiescent current of 2.5 mA. The device supports data rates up to 500 kbps and provides 2500 Vrms galvanic isolation. It features a 16-pin SOIC-W package, operates within -40°C to +85°C, and includes thermal shutdown protection.

Feature Summary

• Integrates three-channel digital isolator with RS-485 transceiver using iCoupler technology
• Provides high common-mode transient immunity exceeding 25 kV/µs
• Includes true fail-safe receiver for known output states during open inputs
• Features slew-rate limited drivers to minimize transmission line reflections

Applications

• Industrial automation control networks
• Building management systems
• Isolated RS-485 communication interfaces

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration. Ensure compatibility with required isolation voltage ratings and operating temperature ranges for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring robust electrical isolation in noisy industrial environments. It is suitable where low power consumption and high noise immunity are critical. Verify that the 500 kbps data rate meets system requirements and that the 16-pin SOIC-W footprint fits the design constraints.

Part Context

This part belongs to the ADM2483 family of isolated transceivers from Analog Devices. It combines a standard RS-485 driver/receiver with a high-speed digital isolator. The REEL suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Check for ADM2483 variants with different suffixes (e.g., BRZ) for lead-free compliance. Evaluate ADM2482E series for higher speed requirements, noting differences in data rate and pinout compatibility.
